Figure 2 is a fragmentary view, in section and upon an enlarged scale,of parts of the body portion of the receptacle.

Figure 3 is a perspective view of one of the heat absorbing elements.

Figure 4 is a perspective view of an abutment plate.

Figure 54s a perspective view of another form of abutment plate employedin the receptacle.

The receptacle can be of any suitable contour and formed of a bodyportion and a cover. As

showing an embodiment of the invention the receptacle is illustrated, byway of example of polygonal contour and is so constructed as to providea substantially continuous vacuum wall throughout the top, bottom, andsides and ends thereof. The body portion is referred to generally by thereference character i and the cover generally by the reference character2, and which provide a storage chamber.

The body portion comprises an outer section 3 and an inner section 4 oflike contour. but with the inner section 4' of less width, height andbreadth than the width, height and breadth of the outer section 3. Theupper ends of the sections 3 and I are arranged in alignment and thesection 4 is spaced from the section 3 to provide a chamber extendingaround the bottom, sides and ends of the section 4. Such chamber isindicated at I and provides a vacuum space to be hereinafter referredto. The chamber 5 can be of any suitable width, depending upon the posi-The section 3 is imperforate, other than formed near its bottom with anopening 6, to provide for connecting therewith a valve controlled airdischarge pipe 1 adapted to be connected with 'a pump for creating thevacuum in the space 5.

It-will be. understood that the valve controlled pipe I can bepositioned at any point on the section 3 as desired.

Each side wall of the section 3, only two of which are shown, hassecured to its inner face a lower and an intermediate row of abutmentplates 8 and an upper row of abutment plates 9.

The rows of plates 8 are spaced from each otherthree are employed. Theplates 3 are square in contour .and formed with a pair of spacedopenwith the bevel formed on that face which opposes the inner face ofthe walls of the section 4. The

bevel ll overhangs the lower portion of the plate 3 and the latter isformed with openings l2 for the passage of holdfast devices to securethe plates 3 to the inner face of the walls of the section 3. The upperface or inner face of the bottom of the section 3 is formed with a pairof outer and an intermediate row of abutment plates l3. The plates ofeach row are arranged in spaced relation and preferably the number ofplates of a row is three. The plates l3 correspond in contour to theplates 3 or in other words the plates l3 are constructed in the samemanner as the plates 3. The holdfast devices for securing the plates 3in position are indicated at l4. The holdfast devices for securing theplates,

3 and I3 in position are not shown butholdfast devices similar to theholdfast devices 14 are employed for securing the plates 3 and I3 to theinner face of the section 3.

coextensive with the top of each section is a right angularly disposedinwardly extending flange l5, which in cross section is of a lengthslightly less than half the width of the chamber i. The section 3 at thetop thereof is formed with an angle shaped rib l3,.which is. coextensivewith said top and includes a horizontal and a vertical portion and withthe vertical portion spaced from the outer face of the section 3 toprovide a pocket 11 which is coextensive with the section 3. Thevertical portion l1 extends slightly above the top edge of the section3. The function of the pocket l1 will be presently referred to. Owing tothe extending of the vertical portion of the rib l3 above the top edgeof the section 3, the inner side wallof said pocket is of less heightthan the outer side 'wall thereof, see Figure l.

The walls and bottom of the section 4 are provided with parallel rows ofspaced openings. The number of rows of openings formed in the walls ofthe section 4 correspond in number to the number of rows of abutmentplates carried by the walls of the section 3. The number of rows ofopenings in the bottom of the section 4 correspond in number to thenumber of rows of abutment plates l3 carried by the bottom of thesection 3. The openings of the rows formed in the walls of the section 4are indicated at i3 and the openings formed in the bottom of the section4 are indicated at l3.

The upper rows of openings formed in th walls of the section 4 arearranged below the rows of abutment plates 3, but the other rows ofopenings formed in the walls of the section 4 are arranged in alignmentwith the rows of abutment plates 3. and the rows of openings formed inthe bottom of the section 4 are arranged in alignment with the rows ofabutment plates l3. With reference to Figure 2 the section 4 has bothfaces thereof provided with mortises indicated at 23, 2| and eachmortise 23 surrounds the inner end of an opening and each mortise 2|surrounds the outer end of an opening. Mountedin'eachopeningprovidedinthe section 4. other thanthe oftheupperrows ofopenings relation and exerts and resists pressure.

cylindrical members are not compressible and formed in the walls of saidsection 4, is a threaded sleeve 22 having a countersunk portion 23 atits outer end and further having each end formed with a lateral flangeand with said flanges indicated at 24, 23. The flange 24 is seated inthe mortise 23 and the flange 23 in mortise 2|. The flanges areconnected together by holdfast devices 23 and which extend through thebody portion of the section 4.

The sleeves arranged in the upper rows of openings formed in the wallsof the section 4 are constructed in the same manner as the sleeves 22with this exception that the sleeve is constructed to form an upwardlyinclined bore. The sleeves mounted in the upper row of openings formedin the walls of thesction 4 are indicated at 21, and said sleeves 21'are secured to the receptacle 4 in the same manner as the sleeves 22.The inclination of the bore or opening formed by the sleeves 21 istowards the bevelled upper portions of the plates 3. The sleeves 21 areprovided with threads in the same manner as the sleeves 22. Extendingthrough each of the sleeves 22, which are secured in the walls of thesection 4, are threaded, cylindrical members 23 having heads countersunkin the sleeves and formed with pointed'ends 23 which abut against theplates 3. Extending through the sleeves 22 carried by the bottom of thesection 4, as well as threadably engaging such sleeves, are cylindricalmembers 33, having pointed ends 3| which abut against the plate I3.Extending through the sleeves 21, as well as having threaded engagementtherewith, are upwardly inclined cylindrical members 32, having pointedends 33 which abut against the bevelled portions ll of the plates 3. Themembers 23, 33 and 32 in connection with the plates 3, 3 and I3 providemeans for maintaining the sections 3 and 4 in spaced The they have aminimum contact relative to the sections 3 and 4, more particularly thesection 3 so that little or no heat can be conveyed. The braces, 3, 3,l3, sleeves 22 and 21 and the threaded cylindrical members provide whatmay be termed an intrawall structure andform the body portion I as aunit, or in other words form the elements of the body portion I as a.single unit. The cylindrical members connect the sections together bywedge pressure making them immovable relatively to each other.

The top of the chamber 5 is closed by a sealing member 34 ofchannel-shaped cross section and which is secured upon the flanges l5and has the outer side thereof mounted in the pocket |1.'

The upper face of the member 34 is flush with the top edge of thevertical portion of the rib iii. The inner side of the member 34 engagesthe inner face of the section '4. The member 34 provides edge insulationand is constructed of material of very low conductivity having acomparatively thin body portion with respect to the walls of thesections of the body portion. Preferably the material from which member34 is constructed is flbrous. The member 34 is termed a septum and abutsa like member 34 carried by the top 2, whereby when the members 34 and35 are in abutting engagement a substantially continuous vacuum space isprovided throughout the cover and body portion, as the member 33closesthe bottom of a chamber 33 formed throughout the section 2 andwhich provides a Positioned in thatpart oi the chamber I formed by thebottoms of the sections 8, 4 is aheat insulating element 81. Positionedbetween the opposed sides of the sections 8, 4 are heat insulatingelements 88. The elements 88 have their lower portions opposing andspaced from the element 81'.

portion 48 atone end is formed with exhaust ports 43 each associatedwith a compartment 42 to provide for the exhaust of air therefrom toform a vacuum in connection with the chamber 5. The body portion of theelement 81 is formed with transversely extending sleeves 44 for thepassage of the cylindrical members 88 whereby the openings provided byeach sleeve is closed to the compartments 42. Each of the elements 88 isformed with transversely extending sleeves 45 and upwardly inclinedsleeves 48 for the passage of the cylindrical members. The sleeves 44.and 45 in connection with the cylindrical membersprevent the elements81 and 38 from shifting. The body portion 48, as well as the partitions4|, is formed from highly polished material.

The cover element 2 is formed of twoopposed spaced sections 41, 48 ofthe same contour as the sections 8, 4 but oppositely disposed withrespect to these latter sections. The sections 41, 48 provide thechamber 36.

The cover element 2 is of less height than th body portion I and theparts of the sections 41 and. 48 of the cover element 2 corresponding tosimilar parts of the body. portion l are provided with correspondingreference characters, As the sides of the sections 48 are of less heightthan the sides of the section 41, the sleeves 21 are only employed; Thesleeves 21 of the section 48 are oppositely disposed with respect to thesleeves 21 of the section 4. The plates 8 are not employed in connectionwith the sides of the section 41, only the plates 8. The plates 9employed in connection with section 48 are oppositely disposed withrespect to the plates 9 carried by the section 8. Mounted between thesides of the sections 41 and 48 are heat insulating elements 49 of lessheight than the heat insulating elements 88 and arranged between the topwalls of the cover element 2 is a heat insulating element 58 of the samesize as the heat absorbing element 81.

The elements 48 and 58 are similar in form to the elements 81 and 38,with this exception that the elements 48 are not provided with thesleeves 45, but with the sleeves 46. However the sleeves 48 v of theelements 48 are oppositely disposed with respect to the sleeves 48 ofthe elements 88. The

cover element 2 carries an angle shaped rib on its outer side at itsbottom, as indicated at 5|, and

which provides a pocket 52 for the outerside of the sealing member 85.The sections 41 and 48 at their lower ends are provided with inwardlyextending right angularly disposed flanges 58, 54

similar to the flanges l5 carried by the sections 8, 4 at the topthereof.

The elements 88 are spaced from the member 84. The elements 81 and 88are ar- A vacuum wall receptaclain with this invention providessubstantially a perfect insulation from heat whereby the contentsthereof will be protected from the eflects or heat and. preserved for anindefinite period, as well as setting up a receptacle having asubstantially continuous vacuum space extending entirely throughout thesame, that is'through the body portion and cover of the receptacle andfurther whereby with the heat insulating means arranged in the vacuumspace assists in the preserving of'thecontents of the receptacle, andtherefore it is thought the many advantages of a vacuum wall receptacle,in accordance with this invention can be readily understood, andalthough the preferred embodiment of the invention is as illustrated anddescribed, yet it is to be understood that changes in the details ofconstruction can be had, which will fall within the scope of theinvention as claimed.
